Revenue from Contract with Customer [Abstract]

Revenue Recognition

REVENUE RECOGNITION

The majority of our revenue is generated from our sale of gas customers within the regional industrial gases segments. We distribute gases through either our on-site or merchant supply mode depending on various factors, including the customer's volume requirements and location. We also design and manufacture equipment for air separation, hydrocarbon recovery and purification, and liquid helium and liquid hydrogen transport and storage. The Corporate and other segment serves our sale of equipment customers.

Disaggregation of Revenue

The tables provided below present our consolidated sales disaggregated by supply mode for each of our reportable segments for the third quarter and first nine months of fiscal years 2025 and 2024. We believe this presentation best depicts the nature, timing, type of customer, and contract terms for our sales.

Interest income associated with financing and lease arrangements accounted for approximately 1% of our total consolidated sales for the periods presented.

Remaining Performance Obligations

As of 30 June 2025, the transaction price allocated to remaining performance obligations is estimated to be approximately $26 billion. This amount includes fixed-charge contract provisions associated with our on-site and sale of equipment supply modes. We estimate that approximately half of this revenue will be recognized over the next five years and the balance thereafter.

Our remaining performance obligations do not include (1) expected revenue associated with new on-site plants that are not yet on-stream; (2) consideration associated with contracts that have an expected duration of less than one year; and (3) variable consideration for which we recognize revenue at the amount to which we have the right to invoice, including energy cost pass-through to customers.

In the future, actual amounts will differ due to events outside of our control, including, but not limited to, inflationary price escalations; currency exchange rates; and amended, terminated, or renewed contracts.
